Draw the configurational stereoisomers for this structure

A closed container in lab contains a sample of oxygen gas. When the temperature in lab is 14.3 degrees Celcius, the pressure in the container is 10.3 atm. What would the temperature in lab be (in Celcius) if the pressure in the container was 24.0 atm? Assume the mol and volume of the container are constant. Record your answer as a number with the correct significant figures.

Explain the geometrical and optical isomerism of coordination compounds with coordination number 4, giving a suitable example (Minimum 4 examples).

Assuming a total pressure of 9.5 atm, what is the partial pressure of each component in the mixture of 98% helium and 2.0% oxygen breathed by deep sea divers? How does the partial pressure of oxygen in diving gas compare with its partial pressure in normal air?

A helium gas cylinder of the sort used to fill balloons has a volume of 180 L and and a pressure of 2200 psi ( 150 atm) at 25° C. How many moles of helium are in the tank? How many grams?

For the reaction H2(g) + l2(g) = 2 HI(g), equilibrium concentrations at 25°C are [H2] = 0.0510 mol/L, [ I2] = 0. 174 mol/ L, and [ HI ] = 0.507 mol/L.
